Dita Dermalo was one of the 77 woredas in the Southern Nations, Nationalities, and Peoples' Region of Ethiopia. Part of the Gamo Gofa Zone, Dita Dermalo was bordered on the south by Bonke, on the southwest by Kemba, on the west by Zala Ubamale, on the north by Kucha, and on the east by Chencha. Towns in Dita Dermalo included Wacha and Zeda. Dita Dermalo was separated to Dita and Deramalo woredas.
Rivers in this woreda include the Zage. Dita Dermalo is part of a region known for hilly and undulating midland and upper lowland terrain; due to terrain and weather patterns, less than one in five households is food secure. Food crops include maize, enset, sweet potatoes, taro, teff, and yams; income sources include butter and selling firewood.
Although this woreda was in existence before the incorporation of the Federal Democratic Republic of Ethiopia under the name of "Dita", its current area dates from 1996. That year the adjacent woreda of "Dera-Malo" lost its lowlands to Kucha, and the highlands of that woreda joined to Dita to become Dita Dermalo.
Based on figures published by the Central Statistical Agency in 2005, this woreda has an estimated total population of 154,573, of whom 78,505 are men and 76,068 are women; 2,099 or 1.36% of its population are urban dwellers, which is less than the Zone average of 8.5%. With an estimated area of 654.85 square kilometers, Dita Dermalo has an estimated population density of 236 people per square kilometer, which is greater than the Zone average of 156.5.
